RJ Lock - Patented One-Of-A-Kind Trailer Hitch-ball Lock

A patented trailer Hitch-ball lock for added theft protection! The RJ Lock prevents someone from unscrewing the nut under the ball and stealing your unattended trailer or anything else you may be towing. Even with the typical hitch-pin and coupler locks in place, one can easily remove the nut with a wrench and move the ball onto another hitch and drive away with your equipment. The RJ Lock is designed to prevent one more way someone can steal your expensive property. Installation is as easy as 1, 2, 3. Remove your existing ball mount nut and replace with the RJ Lock. This patented lock is designed to fit your existing ball mount with a 1 inch diameter shank.

Every component of the RJ Lock is built for ultimate strength and corrosion protection. The major components are built from an anodized solid billet aluminum housing and a dense plated carbon steel fitting. The keyed lock within the housing is custom made of stainless steel and brass. This lock will not rust!

Just like a typical ball mount nut, you leave the RJ Lock attached whether you're towing something or not. No need to constantly remove and re-attached this lock, unless on occasion you're moving it from one ball mount to another. The RJ Lock is added piece of mind to protect your expensive boat, trailer or anything else you're towing. Your satisfaction is guaranteed.

NOTE: Ball mounts come in 3 ball shank sizes (3/4", 1" and 1 1/4"). RJ Lock is designed to fit 1" ball mount shanks, which typically have 2" or 2 1/4" balls.
